# azure-ai-language-questionanswering — Microsoft Azure Question Answering Client Library for Python

License: permissive · Maintenance: active · Downloads: 77.7K/mo

## What it is and what it does

This is Microsoft's official Python SDK for Azure's Question Answering service, a cloud-based API that lets you build conversational Q&A layers over your data. It provides two main client classes: QuestionAnsweringClient for querying knowledge bases and getting answers, and AuthoringClient for managing QA projects (creating, deploying, updating knowledge sources). The library handles authentication via API keys or Azure Active Directory, supports both synchronous and asynchronous operations, and abstracts the HTTP communication through its azure-core dependency.

You use it when you have a knowledge base of questions and answers (built from FAQs, manuals, or documents) and need to programmatically query it for the best matching answers, optionally with follow-up conversation support. The service learns from user behavior to improve answer quality over time. It's part of Azure's Cognitive Services ecosystem and integrates with the broader Azure SDK for Python.

Use it for:

- Build a chatbot backend that retrieves answers from a company FAQ or knowledge base.
- Integrate question-answering into a customer support portal or help system.
- Automate knowledge base management by programmatically adding or updating QA pairs.
- Deploy and manage multiple QA projects across different environments or use cases.
- Add conversational follow-up capabilities to existing FAQ systems.

## Worth the install?

AI-flagged interpretation of the facts above — verify before relying.

Python client library for Azure's Question Answering service, enabling you to query knowledge bases and manage question-answer projects via cloud API.

Yes. This is a stable, actively maintained official Azure SDK with low install friction, permissive licensing, and no known vulnerabilities. Install it if you need to query or manage Azure Question Answering services from Python; it's the only supported way to do so. The main prerequisite is having an Azure account and Language Service resource already provisioned.

## Install

pip install azure-ai-language-questionanswering
uv add azure-ai-language-questionanswering
poetry add azure-ai-language-questionanswering

## Installing azure-ai-language-questionanswering

Before you install: Low install friction with only two runtime dependencies (azure-core, isodate). Active maintenance status and recent release history indicate ongoing support.

License in practice: MIT License permits commercial and private use with minimal restrictions; you may use, modify, and distribute this package freely provided you include the license notice.

Quickstart:

pip install azure-ai-language-questionanswering

from azure.core.credentials import AzureKeyCredential
from azure.ai.language.questionanswering import QuestionAnsweringClient

client = QuestionAnsweringClient(endpoint, AzureKeyCredential(api_key))
output = client.get_answers(question="...", project_name="...", deployment_name="...")

Requires Python 3.7 or later; you must have an Azure subscription and Language Service resource with endpoint and API key.

Verify before relying:

- Whether the service API version 2021-10-01 default meets your application's compatibility needs.
- Specific performance characteristics or rate limits for your expected query volume.
